PSOC6.py: remove silicon ID check

PSoC 6 hex files contain 4-byte chip ID at virtual offset 0x90500002
added by PSoC Creator or cymcuelftool from .cymeta ELF section.
merge_images compares chip ID in CM0+ and CM4 hex files and raises
an exception in case of mismatch. Chip ID is different for each MPN
(for example, 0xE2072100 for CY8C6347BZI-BLD53 and 0xE2062100 for
CY8C6247BZI-D54). CM0+ prebuilt images target CY8C6347BZI-BLD53
but should be compatible with other PSoC6 MPNs.
Remove the check to enable merging CM0+ images with CM4 applications
built for different MPNs, with empty or absent cymetadata.
